Shaker deletes referenced export

[yepitschunked]

Environment

• wyw-in-js version: 0.5.4
• custom processor: N/A
• Bundler (+ version): webpack 5.93.0
• Node.js version: 20.9.0
• OS: codesandbox

Description

See the attached codesandbox link for code layout.

index.js imports Spring from dep.js. Shaker deletes the fallback export in dep.js even though it's referenced by Spring:

  wyw-in-js:transform:00001#1->00002#1 create EvaluatedEntrypoint for [ 'Spring' ] +115ms
  wyw-in-js:cache:entrypoints 00002:add /project/workspace/src/dep.js "updated" +1ms
  wyw-in-js:transform:00001#1->00002#1:module evaluate +1ms
  wyw-in-js:transform:00001#1->00002#1:module:source "use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
exports.Spring = void 0;
exports.spring = spring;
function spring() {
  return "spring";
}
const Spring = exports.Spring = {
  fallback,
  create: spring
}; +0ms

This results in a ReferenceError when evaluating the module since fallback is an undeclared variable.

The problem goes away if I either:

• stop exporting fallback
• rename the parameter in fallback to something else
• remove the parameter in fallback
